Your server collation is SQL_Latin1_General_CP1_CI_AS. You have a database named Contoso that has a collation setting of SQL_Scandinavian_Cp850_CI_AS. You create and populate a temporary table #Person from table dbo.Person in Contoso using the following statements:

use MyDB;
CREATE TABLE #Person (LastName nchar(128));
INSERT INTO #Person SELECT LastName FROM dbo.Person;
You then run the following command:
SELECT * FROM dbo.Person a JOIN #Person b
ON a.LastName = b.LastName;

This command returns the following error:
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "SQL_Scandinavian_Cp850_CI_AS" in the equal to operation.
You need to resolve the collation conflict. Which Transact-SQL statement should you use?

A.
CREATE TABLE #Person (LastName nvarchar(128) SPARSE);

B.
CREATE TABLE #Person (LastName nvarchar(128) COLLATE database_default);

C.
CREATE TABLE #Person (LastName nvarchar(128) COLLATE SQL_Latin1_General_CP1_CI_AS);

D.
CREATE TABLE tmpPerson (LastName nvarchar(128) COLLATE SQL_Latin1_General_CP1_CI_AS);
